中文摘要

得益于正弦输入电流和高转换效率,降压型有源三次谐波注入变换器备受关注。然而,该类变换器在理论与实践中仍面临直流母线电容导致的浪涌电流及输入失真等挑战。本文提出了一种新型两级矩阵变换器,旨在优化谐波注入性能并提升系统整体效率。

English Abstract

Due to the merits of sinusoidal input currents and excellent conversion efficiency, buck-type active third-harmonic injection converters have received increasing attention in recent years. However, three major problems of these converters still exist in theory and practice. First, the existence of the dc-link capacitor, utilized by early researchers, causes inrush transient and distorts the input ...
